Epoxy Garage Floor Cost: A UK Price Guide
Most epoxy garage floors in the UK cost between £40 and £90 per square metre supplied and installed, which puts a typical single garage somewhere around £1,000 to £2,500 and a double garage around £1,800 to £4,000. The main variables are the condition of the concrete underneath, the system you choose and the finish with a flake or high-build floor costing more than a plain coating. The only way to get an accurate price is to have the floor assessed and the ranges below are indicative market figures, not a Surface Specialists quote.
Key takeaways
- Typical range: around £40 to £90 per m2 installed, so most single garages land between £1,000 and £2,500.
- The concrete decides a lot: a sound slab is cheap to coat; a cracked, oily or damp floor needs repair first, which adds cost.
- Finish moves the price: a plain coating costs less than a decorative flake or high-build floor.
- Size brings the rate down: a double garage usually costs less per m2 than a single because setup costs are spread further.
- Get it assessed: slab condition and moisture can only be judged properly on site, so treat all online figures as a guide.
How much does an epoxy garage floor cost?
As a rule of thumb, an epoxy garage floor in the UK costs roughly £40 to £90 per square metre supplied and installed in 2026 with a basic single-colour coating at the lower end and a flake or high-build system towards the top. For a standard single garage of around 18 m2 that works out at about £1,000 to £2,500. A double garage of 30 to 36 m2 typically runs £1,800 to £4,000 with the rate per m2 usually falling a little as the floor gets bigger.
These are indicative market ranges to help you budget, not a Surface Specialists quote. The price for a garage floor is genuinely project-specific and two garages of the same size can differ by hundreds of pounds depending on the state of the concrete and the finish you want.
Epoxy garage floor cost by size
The table below gives a rough installed cost by garage size, assuming a sound concrete slab that needs preparation rather than major repair. Add to these figures if the floor needs crack repair, levelling or a moisture barrier.
| Garage size | Typical area | Indicative installed cost |
|---|---|---|
| Single garage | 15 to 18 m2 | £1,000 to £2,500 |
| One and a half | 20 to 25 m2 | £1,400 to £3,000 |
| Double garage | 30 to 36 m2 | £1,800 to £4,000 |
| Triple or large | 45 m2 plus | £2,500 to £5,500 plus |
Notice that the per-square-metre rate tends to fall as the area grows. Setting up, masking, preparing the slab and finishing the edges costs much the same whether the garage is single or double, so on a larger floor those fixed costs are spread across more square metres.
What affects the cost of an epoxy garage floor?
Several factors sit behind the headline rate and understanding them helps you see why quotes vary.
The condition of the concrete. This is the big one. A sound, dry slab can usually be coated after grinding and cleaning, which keeps costs down. A slab that is cracked, pitted, oil-stained or damp needs repair, degreasing or a moisture barrier first and that preparation is often the difference between a cheap quote and an expensive one.
The system and build. A thin single-coat epoxy uses less material than a high-build floor laid in several coats with a sealer over the top. A thicker, tougher build costs more but stands up better to vehicle traffic, tyre marks and dropped tools.
The finish. A plain single colour is the most affordable. Decorative flake, a metallic finish, anti-slip aggregate or a bespoke colour all add material and labour. Flake floors are the popular garage look and sit a little above a plain coating.
The size of the floor. As the table above shows, larger garages cost less per m2. Very small jobs often carry a minimum charge because the setup is the same.
Access and clearing. An empty, swept garage is quicker to prepare than one that has to be worked around stored belongings. Moving and storing contents, or working in sections, adds time and cost.
Why surface preparation drives the price
The most underestimated line in any garage floor quote is preparation. Before epoxy goes down the slab usually needs mechanical grinding or shot blasting to open the surface, plus crack and joint repair and, where moisture is present, a damp-proof primer or membrane. Depending on the state of the floor this can add a meaningful amount to the job.
It is also the work that decides whether the floor lasts. Almost every epoxy garage floor that peels or flakes early does so because it was laid on a poorly prepared or damp slab, which is why subfloor preparation is central to every job we arrange. A low quote that skips it is rarely the bargain it looks like.
Is an epoxy garage floor worth the cost?
An epoxy floor sits above garage floor paint on price but below tiling and what you get for the money is a seamless, hard-wearing surface that resists oil, chemicals and tyre marks, wipes clean and brightens the whole space. A correctly specified and installed epoxy garage floor can last 10 to 15 years or more with very little maintenance, which spreads the upfront cost over a long life.
The value depends entirely on getting the preparation and the system right. A floor matched to how the garage is used, laid over a properly prepared slab, is one of the best-value upgrades a garage can have. One painted on cheap over a dusty or damp slab will not last and ends up costing more to put right than it saved. If you are still weighing the options, our guide to epoxy garage floor vs paint vs tiles compares the three on durability and finish.
Epoxy garage floor cost compared with other options
It helps to see where epoxy sits against the alternatives. The figures below are broad market ranges per square metre installed over a suitable slab, not Surface Specialists quotes and every option varies with the floor’s condition and finish.
| Option | Indicative cost per m2 | Notes |
|---|---|---|
| Garage floor paint | £10 to £25 | Cheapest up front but thin, short-lived and quick to wear under tyres. |
| Epoxy coating | £40 to £90 | Seamless, durable and resistant to oil, chemicals and tyre marks. |
| Flake or high-build epoxy | £55 to £100 | The popular decorative garage finish, tougher and easy to clean. |
| Interlocking floor tiles | £30 to £70 | Quick to fit but jointed, so dirt and damp can get underneath. |
Epoxy usually competes well on whole-life cost rather than headline price. A seamless floor that shrugs off oil and tyre marks for years often works out cheaper than paint reapplied every couple of seasons or tiles that trap dirt at the joints.
How to reduce the cost of an epoxy garage floor
There are sensible ways to keep an epoxy garage floor affordable without cutting corners on quality.
- Start with a sound slab. If your concrete is in good condition, coating it avoids the cost of major crack repair, levelling or a moisture barrier.
- Keep the finish simple. A single colour costs less than a decorative flake, metallic or bespoke finish.
- Clear the garage first. An empty, accessible floor is quicker to prepare and lay than one worked around stored contents.
- Combine with other work. If a team is already on site for related resin work, doing the garage at the same time can spread the setup cost.
What you should not cut is the preparation. Saving money by skipping the grind, the repairs or a moisture barrier is the most common reason an epoxy garage floor fails early, which costs far more to put right than it ever saved.
How to get an accurate epoxy garage floor price
Online ranges are useful for budgeting but they cannot account for your slab, its moisture or your access. To get a real figure you need someone to assess the floor. A good assessment checks the concrete for soundness and damp, measures the area accurately, confirms how the garage is used and specifies the system and preparation before pricing the coating itself.

Frequently asked questions
How much does an epoxy garage floor cost per square metre in the UK?
Indicatively, around £40 to £90 per m2 supplied and installed in 2026 with a plain coating at the lower end and a flake or high-build floor higher. The rate usually falls a little on larger garages. These are market ranges, not a Surface Specialists quote.
How much does it cost to epoxy a single garage floor?
A standard single garage of around 18 m2 typically costs about £1,000 to £2,500 installed, depending on the condition of the slab and the finish. A double garage usually runs £1,800 to £4,000. Both figures assume a sound slab that needs preparation rather than major repair.
Why are some epoxy garage floor quotes so much cheaper than others?
Usually the preparation. A low quote may assume the epoxy goes straight onto your existing slab, while a higher one includes grinding, crack repair or a moisture barrier. Always check what surface preparation each quote includes before comparing them.
Is an epoxy floor better value than garage floor paint?
Over time, usually yes. Paint is far cheaper up front but thin and short-lived, peeling under tyres and wear, while a properly laid epoxy floor lasts many years. Spread over its life, epoxy often works out cheaper than paint reapplied every season or two.
Does an epoxy garage floor need the concrete prepared first?
Almost always. The slab normally needs mechanical grinding or shot blasting to open the surface, plus repairs and a moisture barrier where needed. This preparation is what bonds the epoxy and stops it peeling, so it is a real part of the cost.
How long does an epoxy garage floor last?
A correctly specified and installed epoxy garage floor can last 10 to 15 years or more of normal domestic use with little more than routine cleaning. Good preparation and the right system matter far more to its lifespan than the headline price.
Are there ongoing costs after installation?
Very little. An epoxy garage floor mainly needs sweeping and the occasional wash with a recoat only after years of heavy use. Because it is seamless there are no joints to fail and no loose tiles to lift, so running costs are low.
